Abstract: 304,376. Imperial Chemical Industries, Ltd., Hailwood, A. J., Naunton, W. J. S., and Shepherdson, A. Oct. 21, 1927. Dye preparations; lakes.-Indiarubber, including balata, guttapercha, and like vegetable resins, is coloured by incorporating in the rubber mix a pigment consisting of a vat dye and a finelydivided substratum substantially insoluble in water. The pigments may be obtained by mixing a dispersed paste or suspension of the vat dye with the substratum or by oxidizing an alkaline solution or suspension of the leuco compound of the vat dye in the presence of the substratum, .with or without a protective colloid, or by incorporating the vat dye with the substratum in the presence of a medium, e.g. a benzene hydrocarbon, which exerts a definite small solvent action on the dye. The dispersion of the vat dye and the coating of the substratum may also be effected simultaneously by the comminution process described in Specification 293,896. Suitable substrata are barytes, alumina, whiting, clays, silica, kaolin, talc, asbestos, magnesium carbonate, lithopone, zinc white, and " catalfo." The pigments may be applied as aqueous pastes or as dry powders, and mav contain other admixed chemicals advantageously added to rubber; they are applied to the rubber compounds during the milling or other mixing operation. In examples of the preparation of the pigments, (1) a finely dispersed duranthrene blue suspension in water is mixed with finely-divided china clay, filtered and dried; if a protective colloid is used to obtain the dye dispersion, a precipitant, e.g. barium chloride, may be added to assist in the adsorption of the dye, (2) air is blown through an alkaline solution of the leuco compound of caledon jade green which has been stirred with magnesium carbonate; the product is filtered, dried, and powdered ; (3) the violet dye obtained by anisoylation of 4: 8-diaminoanthrarufin is mixed with magnesium carbonate and boiled with benzene ; the product is filtered, dried and ground to a powder, and (4) an aqueous suspension of caledon jade green is stirred with magnesium carbonate, filtered, dried, powdered, boiled with toluene, and again filtered and dried.

Abstract: 828,724. Stapling machines. L. M. K. MANUFACTURING CO. Ltd. Aug. 19, 1957 [Sept 14, 1956], No. 28185/56. Class 89(3) In a stapling machine, the front plate 12, Fig. 1, of the staple magazine which defines one side of a guideway down which the staples are driven, is formed as part of a separate component 13, Fig. 2, which has limbs, 14 extending within and parallel with the sides of an outer channelshaped magazine body 10, the component 13 being held in position solely by interlocking between the limbs 14 and a channel shaped magazine bar 11 secured within the body 10. The interlocking means between the limbs 14 and bar 11 comprises, in the illustrated embodiment, inwardly turned portions 15 on the limbs which engage openings 17 in the bar 11. The body 10 and bar 11 are secured together by a central rod 20 which passes through pairs of lugs 22, 23, and 24, 25 on the body 10 and bar 11 respectively, the rod serving also to guide a spring 28 which acts upon a staple feeder 29 by way of a bracket 30 having side pieces passing through holes 31 in the feeder 29. The staple driving blade 50 s comprised by one end of a leaf spring 51 riveted to the base 1, the remainder of which spring bears against a channel-shaped member 55 which when the machine is operated, is caused to bear against the staples in the magazine to prevent them from being moved by the feeder until the operating pressure is released. The clinching anvil is carried by an operating arm 2 which together with the body 10 is pivoted to the base 1 by a pin 4. A leaf spring 40 riveted to the body 10 and magazine 11 has a portion 46 which provides for return movement of the operating arm 2 after a staple has been driven,  and has a portion 43 which prevents withdrawal of the rod 20 and also bears against a surface 44 on the arm 2. When the arm 2 is rotated clockwise, a curved surface 45 on the arm 2 is brought to bear against the portion 43 to impose frictional restraint on further movement of the arm. In normal use the magazine 5 is held downwardly over the member 55 by means of small pips on the sides of the member 55 engaging in recesses 65 in the limbs 14 of the component 13. The magazine 5 is raised by disengaging the pips from the recesses 65 for re-loading purposes. The invention is applicable to a stapling machine in which the anvil is mounted on the base and the magazine is mounted in the operating arm. Specification 670,833 is referred to.

Filed: 1949-11-04
Abstract: 670,220. Jointing by forging. ROLLINSON, E. W. (Thompson Products, Inc.). Nov. 4, 1949, No. 28272/49. Class 83 (iv). A rod is connected to a tube by inserting the rod into an end of the tube reduced by swaging, and the part of the rod inside the tube is then upset to conform with the converging tube wall and to form a head of greater diameter than the end of the tube, means being formed to prevent relative axial and rotative movement between the rod and the tube. In the form shown in Fig. 3, the upsetting operation causes the material of the rod end to be extruded through spaced holes 20d punched in the converging wall 20c of the tube thus forming lugs 21c which lock the rod and tube against both axial and rotative movement. In the form shown in Fig. 5, the imperforate converging wall 30c of the tube is wedged between the upset end of the rod and a shoulder 31c formed on the rod. The converging end wall of the tube shown in Fig. 7 has spaced slots 40c cut inwardly from the end and is of hemi-spherical shape formed by a curling-in operation; the rod has an integral skirt portion 41b overlying the curled end of the tube and the upsetting operation causes the material of the rod to be extruded through the slots to form lugs 41e. In another embodiment, Fig. 2 (not shown), a welded bond connects the rod to the end of the tube so as to hold the upset head of the rod tightly against the converging wall of the tube. The upsetting may be carried out when the rod is in heated condition.

As shown, movement of the X-ray tube along rails 8 produces rotation of a pulley 14 by cable 17 and hence rotation of the smaller pulley 15 on the same axle, with consequent displacement of the film 10 along the rails 13 by cable 18, the ratio of the radii of the two pulleys being (G-1). The carriage 9 supporting the film can be fixed at two different vertical positions A and B, and a fine adjustment for the film-object distance permits a choice of several different magnifications. The movement of the source and the film is produced by oil pressure controlled by air pressure (see Division F1).
